In the presence of ionotropic glutamate and GABA (B) receptor antagonists, pressure-application of glycine onto CA3 pyramidal cells induced a current associated with increased chloride conductance, which was inhibited by strychnine.

These pharmacological properties strongly suggest that CA3 neurons express functional strychnine-sensitive glycine receptors containing alpha2 subunits.

In MFBs, focal puff-application of glycine-evoked chloride currents that were blocked by the GlyR antagonist strychnine.
Our results demonstrate that functional presynaptic GlyRs are present on hippocampal mossy fiber terminals and suggest a role of these receptors in the regulation of glutamate release during the development of the mossy fiber--CA3 synapse.

The present results suggest that presynaptic glycine receptors on excitatory nerve terminals might play an important role in the excitability of the dentate gyrus-hilus-CA3 network in physiological and/or pathological conditions.
This facilitatory effect of glycine was blocked by 1 microM strychnine, a specific glycine receptor antagonist, but was not affected by 30 microM picrotoxin.

17681355 Kilb W, Sinning A, Luhmann HJ: Model-specific effects of bumetanide on epileptiform activity in the in-vitro intact hippocampus of the newborn mouse. Neuropharmacology. 2007 Sep;53(4):524-33. Epub 2007 Jun 30.

To evaluate whether bumetanide consistently attenuates epileptiform activity, we investigated the effect of 10 microM bumetanide in five different in-vitro epilepsy models using field potential recordings in the CA3 region of intact mouse hippocampal preparations at postnatal day 4-7.
Inhibition of ligand-gated Cl (-) channels by 10 microM gabazine and 30 microM strychnine induced interictal activity (IA) that was only marginally affected by bumetanide.

The present study determined whether 1-aminocyclopropanecarboxylic acid (ACPC) or D-cycloserine (DCS), both partial agonists of the strychnine-insensitive glycine site on the NMDA receptor ionophore complex, exerted anticonvulsant or neuroprotectant activity in Li-pilo SE.
In contrast, when administered as exposure treatment ACPC enhanced the neural damage in the thalamus and CA3 of the hippocampus suggesting the neuropathology in those regions is mediated by a different subset of NMDA receptors.
